Webhook subscope documentation error


In the webhook API documentation the subscope attribute is defined as follows.

An object that contains an array of column Ids if you want to limit the subscription to a subscope. Specified when a webhook is created and cannot be changed.

But then the example has the following. That is not an array of column ids. That is a string in an array that has a comma separated list of column IDs. I assume that you did not want to include the quotes?

"subscope": {
"columnIds": [
"7318427511613316, 7318427511613123"
